CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right ApplicationNumber 2018/1392, which was filed at Community Plant Variety Office inthe European Union on May 28, 2018, the contents of which are herebyincorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Miniature Rose Plant of the presentinvention was created during 2014 at Offenseth-Sparrieshoop, Germany byartificial pollination wherein two parents were crossed which previouslyhad been studied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., seed parent) of the newvariety was an unnamed seedling (non-patented in the United States). Themale parent (i.e., pollen parent) of the new variety was the ‘KORpot028’variety (U.S. Plant Pat. No. 25,004).

The parentage can be summarized as follows:unnamed seedling x ‘KORpot028’

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new Miniature Rose Plant of the present inventionpossesses the following combination of characteristics:

-   -   (a) forms attractive, double, pink colored blossoms,    -   (b) exhibits an upright growth habit,    -   (c) forms vigorous vegetation, and    -   (d) forms attractive ornamental foliage.

The new variety well meets the needs of the horticultural industry. Itcan be grown to advantage as ornamentation in parks, gardens, publicareas, and in residential settings. Accordingly, the plant isparticularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. Morespecifically, the unnamed seedling seed parent exhibits white coloredflowers, a medium and bushy growth habit, and smaller flowers comparedto the pink colored flowers of the new variety, which exhibits anupright growth habit. Additionally, the ‘KORpot028’ variety (i.e.,pollen parent) exhibits dark red colored flowers and an upright andbushy growth habit, whereas the new variety displays double, pinkcolored flowers and an upright growth habit; additionally, the newvariety exhibits larger flowers compared to the ‘KORpot028’ variety.Moreover, the new variety can be readily distinguished from non-parentalrelated similar varieties. For example, the ‘First Prize’ variety (U.S.Plant Pat. No. 2,774) exhibits larger diameter flowers with lower numberof petals and less globular shaped buds compared to the new variety.

The new variety has been found to undergo asexual propagation in KleinOffenseth-Sparrieshoop, Germany by a number of routes such as vegetativecuttings, typically internodal one node cuttings. Asexual propagationtechniques in Germany, such as vegetative cuttings, typically internodalone node cuttings, have shown that the characteristics of the newvariety are homogeneous, stable, and strictly transmissible by suchasexual propagation from one generation to another. Accordingly, the newvariety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘KORone005’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonablypossible to make the same in color illustrations of this character, atypical specimen of the new variety. The illustrated rose plant of thenew variety was approximately twelve weeks of age and was observed atKlein Offenseth-Sparrieshoop, Germany while growing indoors on its ownroots in 6.0 cm containers.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart, 2015 edition). Theterminology which precedes reference to the chart has been added toindicate the corresponding color in more common terms. The descriptionis based on the observation of a one-year-old specimen of the newvariety, observed during February, while growing in a one-galloncontainer on its own roots in a greenhouse at Cochranville, Pa.

Plants of the ‘KORone005’ variety have not been observed under allpossible environmental conditions to date. Accordingly, it is possiblethat the phenotypic expression may vary somewhat with changes in lightintensity and duration, cultural practices, and other environmentalconditions.
